Article Abstract
Background: We have retrospectively reviewed our series of brain tumor patients operated on using 3D IntraOperative UltraSound (IOUS) to report technical advantages and areas of improvement.
Methods: Clinical and radiological data of patients with a diagnosis of high-grade glioma IV operated with and without IOUS were retrieved and analyzed.
Results: We have found 391 patients operated using IOUS coupled with neuronavigation and 257 using neuronavigation standalone. We have selected a pool of 60 patients with a diagnosis of GlioBlastoma (GB), comparing two equally sized groups operated with and without IOUS, respectively. The average extent of resection (EOR) in the IOUS group was 93%, while in the control group, it was 80%. IOUS was significantly associated with improved EOR ( < 0.0004), even when accounting for other factors affecting EOR. The average overall survival (OS) was 13.4 months, and the average progression-free survival (PFS) was 7.4 months. The Cox proportional hazard model showed an advantage in OS on patients operated using the IOUS. No statistically significant effect was observed on PFS.
Conclusion: Intraoperative ultrasound coupled with image guidance is associated with an improved EOR and possibly an improved OS. While we are aware of several limitations related to the present analysis, these data support the routine use of IOUS as a safe and reliable technology. Larger, prospective series with updated IOUS technology are desirable to verify the accuracy of these results.

Brain tumors are one of the most dangerous cancers with serious effects on human health. The primary treatment approach involves a combination of surgery, supplemented by postoperative radiotherapy. The growth pattern of malignant tumor is typically infiltrative, posing a challenge in visually distinguishing the tumor from the surrounding normal brain tissue during surgery.

Identification of a tumor-bearing portal territory using indocyanine green (ICG) fluorescence imaging (IGFI) facilitates precise laparoscopic anatomic hepatectomy (LAH). However, it is technically challenging to perform a transhepatic portal injection of ICG or to clamp the target portal pedicle and inject ICG during LAH. Herein, we aimed to investigate the feasibility and efficacy of portal territory identification using IGFI under the combined guidance of three-dimensional (3D) virtual imaging and intraoperative ultrasound (IOUS) in LAH.

In patients with gastroenteric and pancreatic neuroendocrine neoplasms (GEP-NENs), the risk of liver metastases is high, but the accuracy of standard imaging for detecting small hepatic nodules is limited. This raises concerns about the adequacy of staging in cM0 patients. This study aims to determine the percentage of cM0 GEP-NEN patients with occult liver metastases that can be identified using intraoperative ultrasound (IOUS) during surgery for the primary tumor.

Introduction: Partial nephrectomy is the gold standard treatment for incidentally detected small renal tumors. To optimize the outcomes, use of intra operative imaging techniques like ultrasound (IOUS), OCT (optical coherence technique) and fluorescence along with augmented reality is indicated. However, these are not available in all the centers and may also not be needed for predominantly exophytic tumors with low RENAL nephrometry scores.

: Intraoperative ultrasound (IOUS) provides real-time imaging during brain tumor surgery but remains underused in brain metastasis resection. This study evaluates the effectiveness of 2D IOUS in improving the extent of resection compared to standard neuronavigation. : We retrospectively analyzed 55 adult patients with brain metastases treated surgically at a single center.
